Best videos of 2010: Ants that mimic fluids

Ant swarms that appear to move like viscous liquids make it to number nine in our roundup of the year's best videos.

The dynamics of ant swarms share an uncanny similarity with the movement of various fluids (see video above).

Micah Streiff and his team from the Georgia Institute of Technology in Atlanta captured writhing groups of ants behaving just like liquids. You can watch them diffuse outwards from a pool, tackle jagged surface like a viscous fluid or flow from a funnel.
